BED FABRIC.

Specification of Letters Patent.

Patented Sept. '7, 1915.

Application filed June 20, 191 i.- SerialNo. 8%;296.

To all whom it may concern Be it known that I, CLARENCE H. FREDEIF ICK, a citizen of the United States, reslding at Ke'nosha, in the county of Kenosha and State of Wisconsin,- have invented certain new and useful Improvements in Bed Fabric, of which the following is a specification.

My invention relates to improvements in bed fabrics and refers more particularly to that type of bed fabric which is constructed of a series of longitudinal link chains arranged in parallel relation and connected together by means of cross-links engaging links of the longitudinal chains, and of the general type shown and described in United States Letters Patent No. 758,920, issued to 0. It. Hunt, May 8, 1904.

The salient objects of my invention are, to provide an improved construction of wire link fabric which shall be transversely and longitudinally foldable and in which the main chain links and the cross-links of the fabric are positively positioned and located so as to prevent them from becoming displaced when the fabric is folded, or at any other time; to provide an improved con struction in which the tension transmitted by the cross-links of the fabric is prevented. from separating, stretching or bending the longitudinal links; to provide an improved construction in which the longitudinal links of the fabric are formed with cross-link eyes so shaped as to prevent their opening up due to the tension of the longitudinal chains of the fabric; to provide a construction in which the links are of comparatively simple form and cheaply and economically manufactured, and, in general, to provide an improved b'ed fabric of the type referred to.

My invention consists in the matters hereinafter described and more particularly pointed out in connection with the accompanying drawings, in wh1ch Figure 1 is a plan view of a portion of my improved bed fabric; Fig. 2 is an enlarged fragmentary section taken on the line 2-2 of Fig. 1; and Fig. 3 is an enlarged fragmentary section taken on the line 8-3 of Fig. 1.

Referring to the drawings, it will be seen that the fabric as a whole is constructed of a series of parallel longitudinal similarly formed chains, each of which is composed of a series of wire links 4. Each of these links 4 is constructed from a single length of wire which is centrally bent back upon itself to form the end eye 5, and the two ends of the wire are brought together at the other end of the link and formed into hooks 6 which engage the end eyes of the adjacent links of the chain; The longitudinal chains are tied together transversely by means of the cross-links 7 which engage eyes 8 formed in the longitudinal links adjacent their hooked ends. These eyes 8 in the longitudinal links are completely closed in order to prevent the cross-links from becoming displaced from any cause, and are formed by making a flat coil loop in the wire at each side of the link, this construction being shown quite clearly in Fig. 3 of the drawings.

Since it is very essential to prevent the hooked ends of the longitudinal links from spreading apart under the tension of the cross-links, these ends are each given a longitudinal axial twist adjacent the crosslink eyes, as indicated at 9. It will be noticed that the cross-link eyes 8 are comparatively small in diameter, and there is practically no tendency of the wire to bend, due to the longitudinal tension of the chains, but even if this did occur this would have no bad effect, since the cross-link eye would simply contract slightly and the cross-links could not escape or become displaced.

It will be readily understood from the above description that the construction is such that it may be folded both transversely and longitudinally without any difliculty, and when so folded or unfolded there is no tendency of the links to stick in improper position or to become accidentally displaced. The links of the fabric are of extremely simple form and can be manufactured with great ease and rapidity by comparatively simple automatic machinery.

Although I have described and shown what I consider to be a preferred embodiment of my invention, it is manifest that certain changes may be made in the precise form of the links without departing from the spirit of my invention, and, in any case, I do not desire to be limited in the use of my invention except as specified in appended claims.

I claim 1. A wire link bed fabric, comprising a plurality of similarly formed longitudinal link chains arranged in substantial parallelism, each link being made from a length of wire bent upon itself intermediate its ends to form the end eye of thelink, the two ends of the wire being bent to form a pairof hooks at the other end'of the link, said hooks' engaging the end eye of the adjacent link link chains arranged in substantial parallel-V ism, eachlink being made-from a length of wire bent upon itself intermediate its ends to form the end eye of the link, the two ends of'the wire being bent to form a pair of hooks at the other end of the link, said hooks engaging the end eye of the adjacent link of the chain, the link being given a longitudinal twist adjacent its hook end and being provided with a pair of opposite cross-link eyes intermediate the twist and the hook end, and cross-links engaging said eyes for tying the longitudinal chains together.

3. A wire link bed fabric, comprising a plurality of similarly formed longitudinal link chains arranged in substantial parallelism, each link being made from a length of wire bent upon itself intermediate its ends to form the end eye of the link, the two ends of the wire being bent to form a pair of hooks at the other end of the link, said hooks engaging the end eye of the adjacent link of the chain, the link being given a longitudinal twist intermediate the length of the link and being provided with a pair of opposite completely closed loop eyes adjacent the twist, and cross-links engaging said eyes for tying the longitudinal chains together.
